Greg Krueger is from Minnesota, and he loves his cats. He loves them so much, in fact, that he created a kitty amusement park inside his house just for them to enjoy. His home is criss-crossed with walkways, cat-sized staircases and wonderful, hidden cubby-holes just for the furry felines to romp and relax in. Check out these pictures!

Greg was diagnosed with Asperger's Syndrome at the age of 49, and enjoys coming up with new and creative additions to his cat wonderland.

My cats would freaking LOVE something like this. How incredible would that be?
